I’m having some aluminum and stainless steel parts being made, and I’m curious if anyone knows what surface finish to spec for the sealing surfaces.
For full ocean depth products, it’s usually 32RA microinches. However, I only need my parts to be rated for 400m. I’m thinking something a little less refined, like 63RA, is the way to go.
Hopefully, if one of you BlueRobotics guys see this, you can kindly tell me what you guys spec for the flanges on your aluminum 400m pressure tubes;)
